Random Number Generator, 1-100 No Repeats

Generate numbers from 1 to 100 without duplicates. Each number is drawn once per cycle, making the tool useful for classroom picks, raffles, games, bingo, and fair quick decisions.

A no-repeat random number generator for simple decisions

This tool creates a shuffled pool of the numbers 1 through 100 and draws from that pool one value at a time. Because each value is removed after it appears, the same number cannot be drawn twice in the same cycle.

The design is useful when fairness matters more than speed alone: classroom turns, bingo calls, practice question numbers, party games, light raffles, order selection, and other quick browser-based decisions.

Everything runs in your browser as static HTML, CSS, and JavaScript. There is no sign-in flow, no account requirement, and no server-side storage for the visible sequence.
